Description

A tracer system and method for inducing human social function development

technical field

The present application relates to the technical field of human social functions, in particular to a tracking information system and method for inducing the development of human social functions.

Background technique

It is a very important scientific fact that human beings are the masters of the world today, because human beings have an extraordinary ability called "humanity", and human beings have the generation of nerve cells called "mirror neurons" This generative mechanism does not rely on DNA transmission, but relies on the social storage system of human society itself, which guides the development and differentiation of neurons in human brain cells, and promotes our primitive ancestors to gradually break away from apes. Its function is to reflect the influence of other people's behavior on the structure, development and differentiation of children's brain cells, so that people can learn from simple imitation to more complex imitation, and gradually develop a series of language, music, art, use of tools, etc. Human social function. This is one of the greatest things about human progress.

However, natural sciences and social sciences cannot clearly define this kind of race specificity. The social phylogeny of mirror neurons widely exists in multiple brain regions and participates in activities such as action understanding, imitation, empathy, and social cognition. , is the basis for imitating the actions and learning ability of others, so that the mirror mechanism becomes a bridge for multi-level communication and connection between people. Similar to the neural circuits in the brain that store memories, mirror neurons also appear to "program templates" for specific behaviors. With this property of mirror neurons, basic actions can be made without thinking, and when they are seen, they can be quickly understood without the need for complex reasoning processes. As early as the early 1990s, when studying the firing activity of single neurons in the premotor cortex of monkeys, it was found that the movement of workers in the monkey's visual field can also trigger specific neuron activity. Subsequent further studies have shown that the instinctive behavior of animals can be well explained by the conditioned reflex theory.

But it is not enough to explain the social function of the human body. The human body seems to be an independent physiological child. So far, physiological research has not shown any reliable indication that society affects the development of the human body. So far, it has not been found how the social function of the human body appears, and what kind of induction is needed to appear.

Detailed ways

As shown in FIG. 1 , the first aspect of the application provides a tracer information system for inducing the development of human social functions, including: an information acquisition module 1 , an acquisition module 2 , a signal processing module 3 , and an information information analysis module 4 , data display module 5, storage module 6 and power module 7; wherein,

The information acquisition module 1 includes a plurality of potential detection electrodes with input terminals arranged in different cerebral cortex, each potential detection electrode is correspondingly provided with a voltage amplification circuit, and the input terminal of each potential detection electrode is connected to the input terminal of the voltage amplification circuit.

The potential detection electrode is composed of materials with high conductivity, good stability and biocompatibility, and is used for detecting EEG signals, such as silver material or platinum-iridium alloy plus insulation and connecting wires. When in use, the potential detection electrodes are usually set near the place where the brain noise is generated, and are used to detect the EEG signals around the neurons near the brain noise. The number of potential detection electrodes is not specifically limited, and can be selected according to the test conditions.

The voltage amplifier circuit can use commercially available amplifier circuits, such as single-conductor or multi-conductance physiological amplifiers from Beijing Xintuo Company, which can amplify millivolt or microvolt electrical signals by tens of thousands or hundreds of thousands of times. The input end of the voltage amplifier circuit is connected with the potential detection electrode, and the output end is connected with the input end of the analysis and control module. The potential detection electrode transmits the detected brain wave signal to the voltage amplifier circuit, and the voltage amplifier circuit performs voltage amplification processing on the brain wave signal detected by the potential detection electrode, so that the signal processing module 3 further processes the brain wave signal.

Optionally, the information acquisition module acquires episodic brain waves.

Optionally, the episodic brainwave is an information combination composed of multiple pieces of information, the information combinations have simultaneity probability correlation, the signal components of the information combination have simultaneity correlation, and there is an evoked signal, and the evoked signal is related to the input information. There is a secondary high probability correlation between combinations.

Optionally, the information combination is a source signal combination that has stimulated the child. The source signal combination can generate a doublet neuron pathway. During the process of generating the doublet neuron pathway, secondary brain waves may be triggered. The electrical waves are the tracer signals that generate the neuronal pathways of the doublet.

Occasional brain waves are induced by the simultaneous information structure involving the information combination of multiple information channels. The multiple information channels correspond to different cerebral cortical potential detection electrodes. The simultaneity correlation between information combinations) is correlated, and this correlation is expressed as a probabilistic correlation rather than a deterministic correlation, and this type of information is called brain noise information.

One end of the signal processing module 3 is connected to the input end of the amplifying circuit, and the other end is connected to the information analysis module 4 .

In order to utilize the brain wave signal acquired by the information acquisition module 1, it needs to be processed. For example, when the electrical signal is weak, it needs to be amplified; when it is mixed with noise, it needs to be filtered; when the frequency is not suitable for transmission, it needs to be modulated and demodulated; when the signal is distorted, it needs to be equalized ; When there are many types of signals, it needs to be identified and so on. The process of extracting characteristic signals in the process of event change, and then processing them through de-interference, analysis, synthesis, transformation and operation, so as to obtain the information reflecting the nature of the event change or the information that the processor is interested in. Divided into analog signal processing and digital signal processing. The purpose of signal processing is to attenuate excess content in the signal; filter out mixed noise and interference; or transform the signal into a form that is easy to process, transmit, analyze, and identify for subsequent processing.

Optionally, the signal processing module 3 uses an FIR filter to perform bandpass filtering on the acquired brain waves, so as to obtain relatively obvious relevant desynchronized ERD physiological characteristic data segments.

Exemplarily, as shown in FIG. 3 , the information analysis module 4 can be implemented by using existing electronic components, or can use a microcomputer circuit to implement its functions. When the information analysis module 4 is implemented with the existing electronic components, it is composed of an integrated Schmitt trigger, a NOT gate 1, a NOT gate 2, a capacitor C, a voltage control switch and resistor, and an integrated circuit timer (NE555). The switch consists of switches K1, K2, K3 and corresponding relays M1, M2, M3. The integrated Schmitt trigger can use CD4093. Its function is to compare the voltage. When the voltage is within a certain range, it outputs a low voltage. Otherwise, it outputs a high voltage. The circuit timer (NE555) constitutes a monostable circuit to realize timing. The monostable circuit needs to be triggered by a negative pulse, and the NOT gate 2 realizes the inversion of the voltage V0. When the information analysis module 4 is realized by a microcomputer circuit, a single chip microcomputer is used to run specific software to complete the work of voltage analysis.

The information analysis module identifies the brain waves according to five features. The five features are: (a) a combination of information input from different channels; (b) according to the simultaneity correlation of the elements in the combination, to stimulate the brain. A cluster of marked brainwaves in the cortex; (c) marked brainwaves are associated with high probability of simultaneity of information in the combination; (d) marked brainwaves are associated with high probability of simultaneity correlation mechanism, but the association is not inevitability , but sporadic; (e) this sporadic association exists only within a certain period of time, and after a certain period of time, this association will disappear. The information is input to the information information analysis module (4) through the signal processing module (3) for feature identification.

The acquisition module 2 is connected with the information analysis module 4 . When conducting the human social function test, on the one hand, the information acquisition module 1 is used to obtain the changes of the brain waves of each child during the experiment; The equipment records the pictures and videos of the children's facial expressions, body movements and language changes during the experiment for later comparison. The information analysis module (4) analyzes the time points when infants and young children develop human social functions. The information analysis module (4) can also analyze the pictures and videos of the children's facial expressions, body movements and language changes and secondary information of the causal correlation information of the brain wave tracer signals collected by the information acquisition module (1).

One end of the data display module 5 is connected to the information analysis module 4 , and the other end is connected to the storage module 6 . The data display module 5 displays the analysis results obtained by the information analysis module 4 on the display screen for researchers to view and do further analysis. In addition to a series of functional components, the data display module 5 also includes a display and a power supply as necessary components. .

The storage module 6 records the data in a certain format on the internal or external storage medium of the computer. Here, all the data collected, acquired, analyzed and processed in the system are stored in the computer in a certain format for convenience. Subsequent retrieval, analysis or viewing of data.

The power supply module 7 is respectively connected with the information acquisition module 1 , the acquisition module 2 , the signal processing module 3 , the information analysis module 4 , and the data display module 5 . The power supply module 7 includes a power supply circuit for providing working power for each unit circuit.

Optionally, the stimulation includes using sound, light source signals, or looking in a mirror to induce a new sensory experience for the infant. In a normal environment, the brain noise signals of infants and young children are roughly the same. In order to study when infants and young children acquire this kind of human social function, it is necessary to give infants and young children a stimulus different from the usual environment to promote their own expressions and actions. And some changes in brain activity, and then based on these changes, it is possible to analyze when the human body's social functions first appeared. The stimulus selected in this application is to illuminate various parts of the infant's body with a light source, and the sound source stimulates the infant's hearing or looks in a mirror for the infant, so that the infant can give the infant a new sensory experience, and observe each infant's Change, record at any time, and obtain the brain wave signal during the test.
